The flowers are usually collected in racemes or spike-shaped inflorescences, rarely single flowers (venus slipper, cattleya). The flowers are three-membered, with a double perianth. The sepals are the same, and of the three petals, the middle (morphologically upper) is very different from the others, forming a lip. The lip often has a long outgrowth back, filled with nectar — - a spur. Since the most convenient position for pollination is "lip down", in terrestrial orchids, the flower twists (resupination)during development. Epiphytic orchids with overhanging inflorescences do not require resupination. Almost from all known flowering plants, representatives of the family differ in the fusion of filaments of stamens, which can be one, two or very rarely three, with a column of ginecea in the so-called column, or gynostemia, — such a specific formation is found, in addition to orchids, only in representatives of the family . It is characterized by a significant reduction of androcea; the fusion of pollen grains in the

How to Care for the Plant
Water
During the growing season, water daily or every other day. Be careful, though, because drainage is an absolute priority. The potting media must be perfectly free draining. The plants can also be grown on slabs or in baskets. Because oncidiums have large, fleshy pseudobulbs and masses of roots, they are prone to rot.1
Pruning
According to orchid experts, you should definitely not remove the roots. There's a good chance you'll harm the plant or introduce a dangerous virus. Trim an orchid root or stem only if it's dry and you're certain it's dead, but work carefully to avoid cutting too deep and harming the plant.
Fertilizer
During the growing season, feed with a weak orchid fertilizer bimonthly or scatter slow-release pellets in the growing media at the beginning of the season. Although there are many species, in general, the larger the plant, the more heavily it will feed.
